Solar Electricity
Our 3200 watt array is mounted on a dual-axis tracker, producing 5400 kWh each year. The array consists of sixteen Sanyo HIT-200 panels, each producing 200 watts. The array is on a Wattsun AZ-225 Dual-axis tracker so it follows the sun as it travels through the sky,
Solar Electric Components
The array consists of sixteen Sanyo HIT-200 panels, each producing 200 watts, so our total power is 3200 watts.
The Fronius IG-4000 inverter (below, right) takes 220 V DC from the PV array, and changes it to 240 V AC so it can be sent directly into our breaker box (on the left). If we are generating more energy than our house is using at the moment, the excess energy goes onto the electrical grid and is used by our neighbors.
The array is on a Wattsun AZ-225 Dual-axis tracker so it follows the sun from both east-west and north-south. This improves the production of the array by 25-30%. However I do not recommend tracking systems as they require much more maintenance. Installing 30% more panels may be cheaper, and will definitely require less maintenance.
